呼叫还原异常时，试图调用合同由一个聪明的合同工厂在草帽。

Question

此函数部署一个新的erc721智能契约。它可以工作，因为当我试图从函数中调用契约的实例时，它可以工作。但是，当我写我的硬帽子测试时，这是我得到的错误：

来自原木：

     Error: call revert exception [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (method="name()", data="0x", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.6.4)

来自本地节点：WARNING: Calling an account which is not a contract

我的职能：

    function createCollection(string memory name_, string memory symbol_, string memory baseURI_, uint256 maxSupply,address owner) external returns (address collection) {
        bytes memory bytecode = type(ERC721W).creationCode;
        bytes32 salt = keccak256(abi.encodePacked(name_, symbol_, block.number ));
        assembly {
            collection := create2(0, add(bytecode, 32), mload(bytecode), salt)
        }
        ERC721W(collection).initialize(name_, symbol_, baseURI_, maxSupply, owner);
        console.log('Inside contract', ERC721W(collection).symbol()); // for testing (works)
        allCollections.push(address(collection));
        emit CollectionCreated(name_, symbol_, baseURI_, allCollections.length, address(collection));
        return collection;
    }

我的测试：

    it("Should deploy a contract", async function () {
      const { ercFactory, owner, account1 } = await loadFixture(deployFixture);

      let name = "test";
      let symbol = "tst";
      let baseURI = "https://test";
      let maxSupply = 10;
      let ownerAddress = account1.address;
      let newAddress = await ercFactory.callStatic.createCollection(
        name,
        symbol,
        baseURI,
        maxSupply,
        ownerAddress
      );

      console.log("new address", newAddress);

      let ERC721 = await ethers.getContractAt("ERC721W", newAddress);
      //console.log(ERC721);
      console.log(await ERC721.name());
      console.log(await ethers.provider.getCode(newAddress));
      //expect(await ERC721.owner()).to.be.equal(account1.address);
    });

调用任何函数都会抛出这个错误，我已经全部尝试过了。我没有任何其他合同的同名，所以getContractAt应该在工作。这里不太确定

嘿，你能分享命令行的输出吗.

您是否可以尝试在newAddress中调用像在合同中一样生成的函数，或者是否有任何契约的输出显示？
